2 Claims.

This invention relates to new and useful improvements in spindle mountings for bobbins such as are used with spinning machines and the like, the principal object of the invention being to provide an anti-breakage improvement for spindle bases.

Another important object of the invention is to provide a spindle base appliance which will hold the base and spindle in such a manner that the spindle base does not contact the usual base rail, but is stabilized in such a manner to prevent breakage which easily occurs at present where the bases are directly secured against the base rail.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a fragmentary side elevational view showing one form of the invention.

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a fragmentary side elevational view showing the present invention in vertical section.

Figure 4 is a fragmentary horizontal sectional view taken substantially on a line 4-4 of Figure 1.

Figure 5 is a fragmentary side elevational View showing a modification of the present invention.

Figure 6 is a section on the line 66 of Figure 5.

Figure 7 is a vertical sectional view through portions of the structure representing the present invention and its relationship to the base rail.

Figure 8 is a bottom plan view of the structure shown in Figure 5.

Referring to the drawings wherein like numerals designate like parts, it can be seen that one form of the invention is represented in Figures 1 to 4 inclusive. Numeral 5 denotes the usual base rail for the spindle bases. The spindle base consists of the casting 6 having a plate or flange portion 1 from which depends a shank 8, and heretofore this shank is passed through an opening 9 in base rail 5 with plate I resting directly on the rail 5 and a retaining nut carried by the shank 8 adapted to abut the other side of rail 5.

In carrying out the present invention, a threaded sleeve Ill is employed and has a circumferentially extending head or flange II at its upper end which is adapted for interposition between the rail 5 and the base plate 1. A nut I2 is provided on the threaded sleeve l0 and is tightened snugly against a washer l2 which in turn presses against the under side of the rail 5, thus definitely holding the sleeve in fixed position.

The flange II is formed with radially disposed bores and into these are disposed set screws l3 which can be driven inwardly to bite the shank 8. This will prevent rotation of the shank 8 and base 6 on the upper end of the sleeve ID.

A modification of the invention is shown in Figures 5 to 8 inclusive, and in this form the base rail is denoted by reference character 5a.. Reference character 6a, denotes the base of a spindle mounting which has a base plate Ia. Depending from the base plate la. is a shank 8a having its upper portion threaded as at 8b. Extending through an opening 9a in base rail 5a is a sleeve Illa on which a nut l2a is feedable to a position snugly against a washer l2b which in turn presses against the under side of base rail 5a to hold the sleeve lBa in fixed position with its flanged end Ila interposed between the base plate 1a and the base rail Set.

To prevent rotation of the base 6a upon the' flanged upper end Ha of the sleeve Illa, a nut I4 is provided and feedably disposed on the threaded portion 8b of the shank 8a and between this nut I4 and the lower end of the sleeve Illa is a washer l5. Obviously, by tightening the nut l4 and washer [5 against the lower end of the sleeve Illa after the sleeve has been secured in place with respect to the rail 511 by the nut lZa, base 6a will be prevented from rotation above the rail 5a. Indirect attachment of the spindle base to the rail 5a has a tendency to prevent breakage of the cast bases 6 and 60..

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is 1. In combination a spindle base, a base rail having an opening therein, a bushing having threads thereon and a head at one end for engaging the other side of the base rail, said base having a depending portion extending through the bushing, and retaining means for preventing rotation of the base with respect to the bushing, said means consisting of a set screw disposed through the bushing to bite the depending member.

2. In combination, a spindle base, a base rail invention, what is having an opening therein,atube having threads and a set screw feedable through the flanged thereon, said base being provided with a dependhead of the tube and adapted to bite the uppering member depending through the tube, a cirmost portion of the member depending from cumferentially flanged head at the upper end the base to prevent rotation of the base on the of the tube interposed between the base and the 5 head.

base rail, a nut on the threaded tube adapted to HERMAN T. OVERBEY. be fed against the under side of the base rail,
